Toys built in. Elaborate torture and stimulation gear as part of the outfit. Especially if visible and controllable from the outside. Inflatable plugs and dildos, electrical stimulation boxes with wires going under the suit, catheters connected to bags of fluids and plumbing and hoses to masks.

Anything that strips her of control over her own body and senses, beyond just simple bondage. She doesn't control what she feels or her body, other people do. The outfit makes her a sexual appliance, and by putting it on she is submitting to the erotic desires of others. The more elaborate and invasive, the better.

Oh, also maids. For a lot of the same reasons. Subservience signalling.
